ANGES COMPANY, A CORPO ASSIGNOR T0 MINING W-HEEL-CONNECTOR FOR TUBULAR AXLES.

To all .whom it may concern:

Be it known that I, WALTER D. STocxnY, a citizen of the'United States, residing at Fairmont, in the county of Marion and State of West Virginia, have invented certain ,new and useful Improvements. in

Wheel-Connectors for Tubular Axles, of

' n which the following is a specification.

This invention relates to means for retaining wheels upon tubular axles which do has for its object to provide a simple and durable .means for" connecting each wheel independently'of the other, in a construction of the type referred to.

. In a device of this kind it is desirable to have the connecting means of such nature that itwill not interfere with the rotation 7 of the wheel upon the axle, besides allowing some freedom of relative axial movement'between the wheel and axle and avoiding interference with the use of the bore of theaxle as a reservoir for lubricant. The problem is solved in a manner to conserve these several. considerations, by the device disclosed in the accompanying drawings and described in the following specification.

In said drawings :-Figu re 1 is a vertical axial section showing the improved construc tion; Fig. Qis a section on the line 2 -2,

1; Fig. 3 is a detail View corresponding to a portion of Fig. l but on a larger scale, and Fig. l is a section on the line P- l of Fig. 1.

1 represents the car axle which is conmeans such as the clip or bearing 2, secured by bolts 2* and which is constructed to permit slight axial and rotary m vement of the axle 1; therotary movement being such as the friction' of the wheels and the axial movement being only such as is permitted by the clearance between the end of the axle and the closed endof the wheel hub, or by the limiting collars 1 which are suitably fixed .upon

, the axle.

The Wheels 3 have closed outer ends so that they form the end closures for the tubu- A by a suitable Specification'of Letters Patent. Patented Aug 25, 1914 Application filed January 20, 1914. Serial 170. 813,246.

lar reservoir of the axle and they are limited in outward movement on the axle, by-means of central pins 4 which project through the closed ends of the wheel hubs and receive a suitable securing device such as washers 4 and cotter pins 4. T he central pins 4 are independently connected with the axle through means of T heads 4 which fit diametrically within the ends of the axle and are there secured by through pins 4 which are headed in the cylindrical walls of the axle and finished smooth with the bearing surface 'of the axle. The wheels will be confined mainly by their flanged bearings against the rails on which they run and the rails will thus afford the chief resistance to the lateral thrust of the car body, as well as the thrust of the axle as it impinges against the closed end of the wheel hub. The means for securing the wheel upon the axle will serve its purpose only in the event that abnormal conditions develop.

Vhat I claim is p- 1.. In combination with an open end tubular axle and closed-end wheels fitted thereon, means for securing the wheels against displacement from the axle while permitting both wheels to rotate and move axially with relation to the axle and to each other; said means comprising independent pins projecting centrally from the open ends of the axle and through the closed-ends of the hubs, each pin having independent means for securing it within the bore of the axle without closing the open end.

2. In combination with a tubular axle, wheels-mounted to rotate on the ends thereof and constructed with closed hubs; said.

axle having longitudinal movement in said wheels; mdcpendent means for securing each wheel to the axle comprising pins projecting centrally from the ends of the axle and through the closed hubs. and T heads on said pins secured diametrically in the bore of the axle.
